Suppose, for the purpose of the argument, that the effect is the disappearance of these growths, then the question is, what action or series of actions is set up by the radiation which leads to this In the first instance opinion naturally inclined to the view that the rays had a direct effect upon the malignant cells, and that this action was Author: Sidney Russ. The authors concluded that bone tumors most likely arise from cells that are separated from the bone surface by fibrotic tissue and that have invaded the area at long times after the radium was acquired. Such cells could accumulate average doses in the range of – rad, which is known to induce transformation in cell systems in vitro. A diminished DR. J. C.

The following experiments have, therefore, been made to discover how normal cells behave when grown in vitro under various gaseous by:   The substance contained a new element; chemically very close to barium, it glowed with a faint blue light, which earnt it the name radium from the Latin ‘radius’ that means ray.

may be partly inactivated, leaving a cell no longer sub­ ject to the limitations on growth which control the life of normal cells. A cancer cell has then been created, and its growth and multiplication may eventually show up as a malignant tumour. Much more commonly the damaged cell is unable to grow properly, or cannot reproduce.   Radiotherapy (RT), also known as radiation therapy, is a treatment modality based on the use of high energy rays or radioactive substances, to damage tumoral cells and to halt their growth and division. RT, used alone or in association with different treatments, has been an effective tool for treating cancer for more than by: Abstract. The clonogenic cell survival assay determines the ability of a cell to proliferate indefinitely, thereby retaining its reproductive ability to form a large colony or a clone. This cell is then said to be clonogenic. A cell survival curve is therefore defined as a relationship between the dose of the agent used to produce an insult and Cited by:   Thyroid hormone regulates proliferation and/or differentiated actions of multiple cell types in bone including chondrocytes, osteoblasts and osteoclasts.

  However, several caveats exist when utilizing cells derived from malignant tumors. In this context, the popular SH-SY5Y neuroblastoma cell line and its use in in vitro systems is described. Originally derived from a metastatic bone tumor biopsy, SH-SY5Y (ATCC ® CRL™) cells are a subline of the parental line SK-N-SH (ATCC ® HTB™).Cited by: Cells (ISSN ; CODEN: CELLC6) is an international peer-reviewed open access journal of cell biology, molecular biology, and biophysics.

Tolerogenic dendritic cells (tol-DCs, tDCs, DCregs) are heterogenous pool of dendritic cells with immuno-suppressive properties, priming immune system into tolerogenic state against various antigens. These tolerogenic effects are mostly mediated through regulation of T cells such as inducing T cell anergy, T cell apoptosis and induction of Tregs.   With the development of radiotherapeutic oncology, computer technology and medical imaging technology, radiation therapy has made great progress. Research on the impact and the specific mechanism of radiation on tumors has become a central topic in cancer therapy. According to the traditional view, radiation can directly affect the structure of the DNA double helix, which in turn Cited by: 9.
